Our take on the Member's Mark Split King Adjustable Base

This is a split king adjustable base: two independent halves, each with its own wireless remote, so each sleeper sets head and foot positions separately. It has one-touch anti-snore, zero-gravity and flat presets plus two memory positions, a 750 lb lifting capacity on reinforced steel, and a nonskid deck with a mattress retainer bar. Setup is screwing in six legs and plugging in the power cable, about 10 minutes, no tools. Owners rate it highly and call it strong value against big-name adjustable bases; the main gripe is that the box is heavy enough that one person cannot set it up alone.
